Hi Fibaro Team,    I kindly ask to support me to solve some problems.    1. The ipad where I´m running your app on doesnt ring when it is locked. I have to leave it always on when I want to be notified about a visitor. Thats not really acceptable from several points.  2. The sound is scratchy and there are cuts in transmission, so several words may be missed. Not acceptable for an Intercom at all. 3. I also experienced that the ring function stops working sometimes
